The invention discloses a replay method of sound fields in a three-dimensional local space. In the method, based on a continuous sound source concept, to-be-replayed sound fields and replay sound fields from continuously-distributed replay sound sources are expanded to form spherical harmonic functions; coefficients of the spherical harmonic functions are matched to acquire driving functions of the continuously-distributed replay sound sources; the continuously-distributed replay sound sources and the driving functions thereof are discretized to obtain driving functions of an actually-discretized replay sound source array; and the driving functions are fed back to the replay sound sources for replaying the sound fields and suitable for any type of sound sources. Compared with a spherical harmonic function expansion method, the replay method is used to avoid the problems of matrix inversion and errors possibly caused by the matrix inversion and expand replay regions; and compared with a wave field synthesis method, the replay method can be used to improve the replay accuracy in micro-regions in which replay centers are contained.
